A device of this general character is siniple and inexpensive to produce and may be easily handled by unskilled help. The washing and drying operation is easily and quickly accomplished and the device is especially suited for washing windows of large otlice building, hotels and similar structures.

Having thus described my invention, what I claim is l. A cleaning apparatus of the character set forth comprising a cleaning head having a plurality of apertures therein and conduit connected with said head, a wiping element carried by said head, means for supplying a cleaning fluid to said head, said head having a flange formed thereon about the top and sides of said apertures and forming a hood thereabout whereby to direct the cleaning fiuid against the surfacev being cleansed and to prevent splashing of` the same.

2. A cleaning apparatus of the character set forth comprising a cleaning head having a plurality of apertures therein and a conduit connected with such head, a wiping element projecting from said head, a flange extending from the top and sides of said head and forming a hood about said aper tur s, and means for delivering a cleaning iiuid through said apertures.

3. A cleaning apparatus of the character set forth comprising a hollow cleaning head having a plurality of aperatures arranged at an angle with respect to the central axis of such head, a squeegee or wiper carried by said head and disposed in operative relation to said apertures, a handle pivotally connected to said head, a conduit'connected to said head, a flange extending from the top and sides of said head and forming a hood about said apertures and means for deliver ing a. cleaning iiuid through said apertures.

l. cleaning apparatus of the class described comprising al hollow cleaning head having a plurality of apertures therein, said head having a flange thereon extending about the top and sides thereof whereby to prevent splashing of liquid delivered through said apertures onto a surface being cleaned, a wiping element carried `by said flange, a handle pivotally secured to said head, a conduit connected with said head and having a pair of branches adapted for attachment to the sourcevof air supply and a source of liquid supply respectively, and a valve for selectively controlling the flow of liquid and air through said conduit.

in testimony whereof, I hereunto afiix my signature.
